Hot 100 number-one hits of 2004 (USA)

The Billboard Hot 100 is a chart that ranks the best-performing singles of the United States. Published by Billboard magazine, the data are compiled by Nielsen SoundScan based collectively on each single's weekly physical sales and airplay. In 2004, there were 11 singles that topped the chart. Although there were 12 singles that claimed the top spot in the 52 issues of the chart, hip hop duo Outkast's "Hey Ya!" began its peak position in 2003, and is thus excluded.
